Q (キュー, Kyū) is a software in the world of Hunter × Hunter.[1]


By sending a nine-digit code to a phone company held by the Hunter Association, a Hunter can send and receive information via this special software. There are no logs and no call history, and regular wiretapping systems cannot detect this method of data transfer.[1]

After Basho, Biscuit, Hanzo, Melody, Kurapika and Izunavi had sent their details to the six offers from Princes of the Kakin Empire, Kurapika reminds them that if their clients specified a non-disclosure agreement, they should be using Q as their method to share information between themselves.[1]
